In February 2020, the design office of Transconverter completed the development of a ТKPM90.000000.00TZ design assignment for a РМ90 UHL4 capability recuperator.
Upon that capability recuperator will return the electric energy of three-phase voltage 400 V, 50 Hz, which generates the tested converter during acceptance tests? to three-phase circuit with the voltage 400 V, 50 Hz.

Therefore, the capability recuperator allows to reduce the electric energy expenses during acceptance tests which leads to cost reduction and profit improvement from the sale of the manufactured product by the cost of saved energy.
